A lamp must never be used as a fuse. But if you are asking why lamps sometimes burn out, rather like fuses do, then the reason is because if a voltage greater than its rated voltage appears across its element, its temperature may significantly exceed its design temperature, and the filament will melt.

What is the job of a bulb in a circuit?
The job of the bulb in a circuit is to convert electrical energy to light. It's called the load in the circuit.
Is a fuse considered a load?
No. Fuse is a protective device. A fuse is part of a circuit and does not act as a load and does not cause a voltage drop unless more than the rated current passes through it and it heats up (using up some power and causing a voltage drop) and melts or switches off breaking the circuit.
What is the central component of a robot that makes it act like human?
The central component of a robot that makes it act like human is the positronic brain.
Can capacitance be negative?
no, if it was it would act like inductance.
What is the advantage of fuse over the circuit breaker?
A fuse might be a bit cheaper and the form factor may smaller if size is an issue. If the fuse blows on a regular basis it will of course end up costing more and will be more inconvenient to replace.
What was George Washington's role in the judiciary act of 1789?
He invented the light bulb

What type of energy is turning on a light?
The light bulb uses electrical energy, and produces light, as well as waste heat. The act of turning it on in itself uses a small amount of energy stored in your muscles.
What are two things light acts like?
In some ways light act like waves, in others like particles.
How does light act as it passes through different materials?
It acts like light I guess
Can light blub act as sun and make flower?
If you use fluorescent lighting you will receive flowers on your plants. A regular light bulb will not do the trick. Buy a cheap shop light fixture and put in two long tubes one cool and one warm. Yes- artificial light can be used to grow plants, including flowers. A light bulb may not make enough light. Search for grow light or plant light.
Will the light from a wide light source act like light from a small light source or light from a large light source?
Light from a small light bulb behaves in the same way light from a bigger light bulb. When you say wide, I assume you mean to ask about light from torches. Light travels in straight lines. If light hits a surface, it will be absorbed or reflected, there are no exceptions. So if light is emitted from a 'wide' source, it will be able to travel to a larger area, lighting up more, but at a lower concentration. If the same amount of light is emitted from a large or small source in the form of a beam, the same applies. The smaller the beam, the more concentrated the light.
Is it correct to say that a bulb in a circuit is a resistor?
Yes it is. The filament in a standard incandescent bulb is a type of resistor. An incandescent light bulb contains tungsten which reduces electricity and converts electricity to heat and light. All incandescent bulbs are resistors, but only a fraction of resistors are bulbs. If you want to see if a bulb is a resistor, try adding another bulb in series without changing the voltage. Both bulbs will be very dim. Another way to test this is to get a multimeter and set the meter to the resistance setting. If you get any value other than zero, then it is functioning as a resistor.
What is meant by the term fusing current?
Fusing current for a wire is the current at which the wire will act like a fuse (melt).
Why does your 05 civic act like it red lining 4000rpms and my check engine light is on?
and the check engine light is on
How does light act like wave?
That means that light exhibits some of the phenomena that are typical for waves, such as diffraction and interference.
How do you turn of anti-theft at ecm on 2001 Chevy Express?
Pull the fuse in the fuse box for "Security" Light will stay on for dash saying Security, but the security system will no onger act up and will enable you to start your van forever.
